| 英文摘要: |
| With the rapid development of green communications, energy consumption issue plays more and more important role in cooperative communication strategies and communication systems. Based on cooperative transmission model, a cooperative user selection scheme is proposed in consideration of both energy efficiency and interference factor. With the proposed scheme, the selected cooperative user consumes less energy and receives less interference. Furthermore, the main factor is analyzed to affect system performance, including signal-to-noise ratio (SNR) of source user and cooperative user, distance between source user and cooperative user or base station (BS), and fading factor in the transmission model. Through the proposed scheme, energy consumption and influence of interference are jointly taken into account during the cooperative user selection process. Besides, bit error rate (BER) in proposed scheme is also superior to existing schemes. Simulation results are presented to show the performance improvement of the proposed scheme. |
